TV Ratings: 'American Grit' Eyes Low

The first of back-to-back episodes falls below the 1 million viewers mark.

While many an eyeball was likely fixed to HBO's Game of Thrones, Sunday's broadcast ratings grab went to Big Brother.

The long-running CBS show, continuing a remarkably steady streak considering it airs three nights a week, averaged a 1.9 rating among adults 18-49 and 6.6 million viewers. That was enough to easily win among the Big Four for the evening, though Tuesday's cable returns will guarantee an overall victory for Thrones. CBS' Candy Crush delivered a flat 0.5 rating in the key demo at 9 p.m.

ABC's trio of Celebrity Family Feud (1.0 adults), Steve Harvey's Funderdome (0.7 adults) and $100,000 Pyramid (0.7 adults) were steady on ABC, while back-to-back episodes of American Grit brought a series low to the Fox show. Its first episode averaged just a 0.3 rating among adults 18-49 and only 920,000 viewers before a second episode brought modest upticks.
